Marion Precision Machining LLC

Marion Precision Machining LLC, operating as Dudley Machining and based in Columbia, South Carolina, manufactures precision-machined metal components and fasteners for the Defense Logistics Agency as a prime contractor exclusively—all 30 recent awards are full-and-open, no-set-aside purchase orders. The company is a minority-owned, black American-owned sole proprietorship and a small business manufacturer focused on hardware production for military aviation and maritime platforms.

Marion Precision's capability portfolio is narrow and component-focused. The company delivers threaded standoffs, shouldered shafts, tapered threaded pins, machine thread plugs, straight headless pins, sleeve spacers, mounting plates, and sleeve bearings—low-dollar precision-machined parts and fasteners with typical award values between $85 and $3,420. Representative work includes a $3,420 shouldered-shaft purchase order from DLA Land and Maritime in July 2025, a $2,814.50 threaded-standoff order from DLA Land and Maritime in April 2025, and a $2,276.85 machine-thread-plug order from DLA Aviation in July 2023. All work is performed in-house in Columbia, South Carolina with no subcontractors.

Customer concentration sits almost entirely with Defense Logistics Agency divisions. DLA Aviation has placed 14 awards worth $4 thousand combined potential value, and DLA Land and Maritime has placed 8 awards worth $6 thousand. The Department of the Army Materiel Command's TACOM Life Cycle Management Command accounts for 5 awards worth $15 thousand, while the Air Force Sustainment Center holds a single $24 thousand award—a potential-value outlier in Marion Precision's footprint. The company has served five distinct customer agencies since 2007.

Activity has remained modest and flat. Marion Precision received seven awards in 2022, seven in 2023, four in 2025, and one in 2026 year-to-date. The combined potential value across all 30 awards totals $50 thousand, with $26 thousand obligated (52% realization). Only one award reaches ultimate completion within the next twenty-four months, carrying $3 thousand in potential value and representing minimal recompete exposure. The company operates without parent contracts, vehicles, or IDIQs; each award stands as a separate purchase order on accelerated delivery timelines typically spanning three to twelve months.
